ABI 12W Deep Red 660nm LED Bloom Booster Grow Light Bulb for Flowering and Spectrum Enhancement

Fast delivery & packaged very well. The product was as described. I like that it's output is a very bright red color spectrum, & it does not get hot, but luke warm, but never too hot to handle. It remains cool due to the vented aluminium heat sinks. It's very reliable, & has workedvery well thus far, & I,ve had it for 5 weeks now, & it's used daily. I use the light for red light therapy & beautification. I saw results within a week of use. Skin was bright & clear, pores were reduced in size, & acne scars became subdued, & blended well with my skin tone. The light also makes my hair softer, more manageable, & transforms it to a healthy glow. Family & friends noticed the difference. Very happy with my purchase. Quality light regardless of its intended use or purpose. A great value, when copared to other comparable Red LED lights of similar specs. This unit has no fan or mechanical moving parts, which I advise you to avoid.

Quality product at a great price. I purchased one of these on another site a couple weeks ago. I liked it so much, I bough another one here (better price here, too!). These are high quality pieces, put together well. They are bright enough to use as much as 3 feet above the plants, and my winter, indoor tomatoes have been doing really good with this light. I previously used Phillips Agro-Light 125W incandescent lamps, and my plants struggled. These are far brighter, much, much cooler, and use far lest power at only 18W. With these, one of my tomato plants is already close to 18" tall after only a couple weeks under this light, and it will be blooming soon, only 5 or maybe 6 weeks after I planted the seeds. Growth with these is just incredible. Far more light output than comparable sized 12W units, and the white LED's make things a little less "funny looking" for people. These lights are even brighter (quite a bit brighter) than a competing "24W" grow light that I bought at the same time. One thing, the description is a little different than the product I actually received. The lights I got (both of them) have 12 red LED (the outer circle) and 3 blue and 3 white LEDs (alternating in the inner circle). The photo is accurate (the colors show better in the reflection), but the text has different numbers (I think it says 13 red, 3 blue, 2 white). When I need more, I will definitely buy more of these lights.

Pros: Works. Does not get hot. Light is red . bulbs are white. Seems well built. Have been using it everyday. Cons: I bought it hoping it would help my joint pain after reading reviews from others saying the light worked well for their joint pain. So far , have been using it for 2 weeks daily, and am not finding any relief or improvement in joint pains. Disappointed it is not working for me. addendum: in addition to using on my aching joints, I have been using it on my face and after 3 weeks of almost daily use, I am seeing that my skin looks very very smooth. the lines around my lips have lessened. my face feels "firmer". I am still using it on my arthritic joints with no results, but it is definitely working on my face !!!

WHAT I LIKE: ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 1) The brightness and intensity of the bulbs. These are brighter than a similar light I bought for a similar price from another buyer. 2) The engineering. The light's outer “cage” is designed to dissipate heat. The inner fan provides additional cooling. As a result the light gets very slightly warm, but never hot. 3) The price. Similar or identical lights in a different kind of casing can cost hundreds of dollars. This one is affordably priced. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– I bought both lamps (660 nm and 630 nm) to support my: ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 1) MITOCHONDRIA. As we age, our mitochondria, those little power batteries in our cells, do too. When this happens, they can benefit from a power boost. They love red light, so I'm giving it to 'em, letting the mitochondria in my epidermis soak it up, so they'll keep giving me ATP and other good stuff in return. Not only does the light help to power our mitochondria (think of a rechargeable battery soaking up energy, then being used again), it triggers the creation of NEW mitochondria, i.e., mitochondrial biogenesis. Side note: I like taking CONTRAST SHOWERS: hot/cold/hot/cold. The cold blasts (I end on 3-5 minutes of cold) are also good for mitochondria. I get out of the shower, walk into the living room, and give my skin a blast of red light afterwards…. a one-two punch that leaves me feeling energized when it’s over. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 2) TESTOSTERONE. As the years go by, men's testosterone starts to decline, leading to a variety of unpleasant health consequences. So I'm starting to do things like this specifically to keep my T levels high. My way of using the lamp for testosterone is to stand with in front of a bank of red lights, with another one shining up on my testicles from a couple of inches below. I stand that way for five or ten minutes, either meditating or listening to a podcast. I've read questions about whether these lights are safe to use near the testicles. As long as they're a couple of inches away, I don't believe there is any danger. They emit very little heat, and the visible wavelengths they give off are helpful, not harmful. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 3) HAIR REGROWTH. I've been bald for decades. So no great expectations. But it's fun to try different things. So I've been shining this light down on my bald head for 15 minutes a day, to see if it generates any changes. So far (one week in) I’ve seen a few (dark) hairs spring to life on the otherwise bald top of my head. (We're talking VERY few... I count three hairs so far -- compared to the 100,000 healthy hair follicles we have when we're younger.) So... who knows. Obviously no light will bring DEAD hair follicles back to life. But some dormant follicles could be reactivated. I’m using the light in conjunction with vitamin D cream, which some claim will also help support hair regrowth. UPDATE: After using the lights for a couple of weeks, a few hairs dozen grew back, but I found myself still essentially bald on top. Maybe if I'd kept up the red light therapy on the top of my scalp, something more exciting would have happened. But as it is -- nothing much to report. I've moved on. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 4) NEUROPATHY. I started having pain in a part of my body a few years ago. I spoke with a doctor, who told me it was neuropathy, was a consequence of aging, and nothing could be done about it. So I got used to living with it. When I bought these bulbs, I started bathing this part of my anatomy with red light every day. To my great surprise, the pain has diminished to a point where it's barely noticeable. I'm thinking now that the pain may be totally healed, given time.

This bad boy is INDUSTRIAL GRADE! I am using it for red light therapy---I had hoped to use it like a "wand" in my hand. It's big, and it's heavy--plus, it has these big ridge fins all the way around it, which makes it unfriendly to hand and face alike. That being said, it's still a terrific buy as a therapeutic instrument. I ended up cutting off a tube sock to cover those fins--but still, it needs to sit in something as a stand. So, here is my "light therapy station" at my desk! I have used it three times now---my eyes feel wider and I feel more awake. Maybe the placebo effect? I have a little (gak: wart) on my little finger that refuses to yield to any and all efforts to get it to go. I "treated" it last night with my bulb---today, it is dry and painless--and hopefully taking the hint. I am open to all kinds of treatments and therapies--I learned about red light therapy after a wrinkle-less friend told me about a $1000 red-light-wand she bought at a trade show. Being WAY TOO CHEAP for that, I did my own research and of course, I found what I needed on Amazon. Here quickly---DELIGHTED! AN ADDENDUM: I am using this bulb regularly on my face (wrinkles and spots) and hands (pain relief). The wrinkles??? Still there. I don't know that they're less visible or affected at all by my low-rent red-light therapy. However, there has been a "chocolate milk" like stain on my upper lip for ages. An "age spot" that refused to yield to any and all lightening creams, it is now a thing of the past! I know it's not my imagination, since it has drawn my eye FOR YEARS. I don't think I gave it any more attention than the rest of my face (during my red-light treatments), but it is GONE. That is worth the price of admission right there! I give my face 10-20 minutes once a day.

We have 6 of these lights. They work ok, but... the 30 degree beam is too narrow. It is a spotlight. Raising it far enough to spread puts it too far away to be fully effective. It takes more than one for any decent sized plant. Second point - one failed. We called Jacobs Parts who said that we must send it back (no big deal) and that the shipping would be reimbursed. They did send a replacement, but refused to refund the shipping, saying that it was over 30 days since puchase, so our tough luck. If they had not lied about the shipping, it may have been easier to accept. SO - BUYER BEWARE! It works, sort of, but the warranty leaves something to be desired! UPDATE - after reading our review, ABI contacted us. They are refunding the price of the bulb to cover the shipping cost, and are sending a new bulb for the inconvenience. We had previously had to return a bulb and had no problems, so maybe this was just an exception to their customer service. Bottom line - they made it ok, but I think that w/o the review we never would have heard from them. There was no appeal from ABI for us to update the review.

I originally wanted it hoping to relieve excruciating pain in my wrist, due to a parvovirus infection. For that purpose it failed. However, I've found a few more personal uses for it: - Treating my psoriasis - Treating idiopathic foot erythema - Face and neck skin anti-aging - Attempting to treat varicose veins Its light has near blinding intensity, not just when looking at the lamp directly, but also when viewing light reflected from a sheet of white paper. This is when the lamp is several inches from the paper, and my eyes are no more than a few feet from that paper. I'm impressed by the vivid redness and intensity of its light, compared to that of an incandescent bulb of far greater wattage that merely has a red colored lens. The explanation must be that, unlike an incandescent, most of its light is innately red, not a mixture of all colors that mix together as "white". I also own one of those red colored bulbs – reflection of its light off a sheet of white paper looks more whitish than reddish. This ABI lamp produces a redder reflection off white paper. In addition to the red light, you can detect ( via warmth on your skin ) its far-infrared radiation ( FIR, i.e. > 3000 nm ). This "heat" emission is given off entirely by the lamp's internal 12 vdc power supply, which has an inherent inefficiency in its conversion from 120 vac. What you probably don't know is that each of the lamp's nominal 660 nm LEDs gives off a considerable amount of near-infrared (NIR) radiation too; actually wayyy more NIR than those low level light therapy (LLLT) panels, pads and wraps that have chips with integral 660+850nm outputs. I have one of those LLLT pads, and also a digital NIR intensity meter. Whereas one of those chips puts out 30-35 W/cm2, if I put my meter's "eye" in contact with this lamp's lens exactly in front of one of its LEDs, there's a whopping 150-160 W/cm2 ! Conversely, when I move the eye over the center of the lens where no LEDs are located, the NIR drops to a meager 6 W/cm2. Moreover, if I move my digital NIR meter 6" away from the center of the lamp's lens, I get 30-35 W/cm2. According to a medical study [ PMID: 34698043 (2021) ] that intensity is the "sweet spot" for optimal NIR LLLT. Note that overexposure to extremely high NIR intensity causes skin aging and cataracts. IMO, it's doubtless that extreme NIR ( and FIR ) intensities will also cause permanent damage to the retina. TIPS FOR LLLT USE Try to position your skin 6" away from the center of the lens, so as to receive an exposure that has a NIR intensity range of safe to optimal. Never get your skin closer to the lens than 5". Wear eye protection that blocks both the red and the IR – I bolster my UV blocking eyeshields with aluminum foil. Cooking your skin and/or deeper tissues is unhealthy. The true function of the adjustable pulsation controller found in most LLLT panels, pads, and wraps is to prevent overheating of tissues. So when your exposure time begins to cause even a little discomfort due to heating, then it's time to either switch this lamp off, or move away from it for a long enough time for your skin temperature to normalize. CONFUSION ABOUT POWER OUTPUT Currently, the Amazon page has a conflicting description : "... 25W of 660nm red light… Pulls a true 25W of power at the wall." The latter part is inaccurate, and the former part is absolutely false. My house has 115.5 vac, and this lamp draws 0.23 amps. So power at the wall is 26.6 W. Most of that power is due to the heat produced by the lamp's internal AC-to-DC converter ( DC power supply ). Assuming that each of the lamp's 18 LED devices are 12 vdc ( typical of outdoor LEDs ), and the 0.550 mA spec given in the description is correct, then the total power output of all 18 of the LED devices is 6.6 W. I'm not sure what is meant in the description by "18x3W Class", but it might mean that the lamp's total lumens are equivalent to that of a 18 x 3 = 54 W incandecent lamp.

Bought this for red light therapy, not for plants, and was pleased at the good quality and quiet operation of the bulb. I also bought a lux meter to determine power density and dosage, and I thought I'd share that info here. I measured the illuminance of the bulb at various distances from a wall, and converted those lux measurements to mW/cm2 (milliwatts per square centimeter) which is the unit of measurement used in all the research related to red light therapy: * 3in (7.5cm) => 1,136,000 lux => 166.3 mW/sqcm * 6in (15cm) => 779,000 lux => 114 mW/sqcm * 12in (30.5cm) => 402,000 lux => 58.9 mW/sqcm * 18in (46cm) => 194,000 lux => 28.4 mW/sqcm * 24in (61cm) => 112,000 lux => 16.4 mW/sqcm I used the illuminance convertor on translatorscafe.com to arrive at these numbers. That convertor is rated for 555nm (which is not the 660nm of this bulb), but the numbers should at least give you a ballpark figure to work from. And just a word of warning, don't point this thing anywhere near your face. Even with your eyes closed and dark tanning goggles on this light is still bright enough to be blindingly bright. EDIT, 5/8/2019: I neglected to factor in the spectral sensitivity for my lux meter (which is only 10% at 660nm), so the power density values have been adjusted.
